【摘要】 本文对可控硅触发电路提出了一种新的设计方法,即采用单片机的一个定时器,三位输出口,外加同步信号检测器和触发信号的驱动电路,构成一个简单实用的三相可控硅触发器,触发角的大小由外部控制信号决定,触发脉冲的宽度由软件参数控制。从而完成可靠、准确地触发。更多还原

【Abstract】 In this paper, a new design of the triggercircuits of the Silicon Controlled Rectifier (SCR) is Presented. The new design uses a single--chip microcomputer, a comp-arer and drivers, the trigger angles are determined by theexternal signals, and the trigger pulse width is controlled bythe software parameters. The trigger circuits are characterizedby their reliability and elactness.更多还原
